INQUA-NL committee 2007-2011

INQUA-NL has reconstituted itself for the current inter-congress period. Wim Hoek succeeds Thijs van Kolfschoten as chair. Jos Deeben (RCE, Archeology) and Jan-Berend Stuut (NIOZ/MARUM, Dust and Marine Geology) have joined as new committee members. Starting 2011, Sjoerd Bohncke (VU-Amsterdam) has replaced Jef Vandenberghe (VU-Amsterdam) as member.

Formal status (definition) of the Quaternary

After long discussions and series of votes, revotes and ratification procedures in INQUA and IUGS subcommisions, The Quaternary is now formally (re)defined as the last 2.6 Ma. See On the Quaternary.


The Quaternary Period in Earth History

The Quaternary Period spans the last 2.6 million years of the Earth's history. It is an interval with dramatic and frequent changes in global climate. Warm interglacials alternated with cold ice ages. The Quaternary saw the global landscape develop into the modern situation. It saw man evolve, become civilised and grow to be a significant factor affecting System Earth.

The broad range of intertwined Quaternary topics spans Global Change, Extinction, Landscape Change, Biodiversity, Greenhouse Warming, Sea level rise, Natural Disasters, Environmental Hazards and Cheese Making. Quaternary Science is a multi-disciplinary effort involving many disciplines such as Geology, Physical Geography, Climatology, Oceanography, Biology, Archeology and Ecology. Quaternary palaeoclimatic investigations play a key role in the understanding of the possible future climate change on our planet.

The Quaternary and the Netherlands

The Netherlands lays on the southern rim of the North Sea Basin, and has been a depocentre of fluvial, shallow marine and glacial sediments during the Cenozoic, including the Quaternary. Quaternary deposits forms the substrate on which the Dutch founded their cities, dug their canals through, build their dykes on and mined their peat, clay and gravel from. Quaternary Geology hence has a long history in the Netherlands, from applied and academic perspectives.

The relatively complete stratigraphy, the interfingering marine and terrestial formations throughout the Quaternary, its presence at the margin of the largest Scandinavian glaciations and pioneering activities of the National Geological Survey in the 1960ies and 1970ies, make the Netherlands host the type localities for many internationally used chronostratigraphical subdivisions of the Quaternary. This includes terms such as: Reuverian and Tiglian at the Pliocene-Pleistocene boundary, the Drenthe substage marking maximum glaciation in the Saalian, the Eemian being the last interglacial and the Hengelo interstadial as a less cold episode within the Last Glacial.

Royal Netherlands Academy of Arts and Sciences

Since 1963, the Netherlands Quaternary community is affiliated with INQUA through the
Royal Netherlands Academy of Arts and Sciences (KNAW). KNAW's former Advisory Council for Earth and Climate (RAK, Raad voor Aarde en Klimaat) has delegated this task to the INQUA-NL Committee. Since 2008, the RAK has merged into KNAW's Council Earth and Life Sciences. Following a policy change in 2009, KNAW covers 50% of the Netherlands' annual membership fee to INQUA.

TNO | Geological Survey of the Netherlands

The Netherlands' Geological Survey (incorporated in the TNO institute since 2000) has long links with the Netherlands' INQUA committee. The geological survey covers 50% of the Netherlands' annual membership fee to INQUA and hosts the committee secretariat.
